Be it known that l, JOHN LALLY, a citizen of the. United States,residing at Boston, Sufioll: County, Massachusetts, have invented a newand useful Improvement in Building Columns, of which the following is aspecification.

My invention relates to buildin columns or the tubular casing, concretelled type with a top or crown built up of cut pieces interlocked withthe casing and it is my object to provide such columns with improvedmeans for attaching floor beams and the like and with means forconnecting superimposed columns which means will be as small and lightas possible and at the same time havegreat weight bearing capacity.

Tn the drawings Fig. 1 is a side view, partly in section of a column topembodying my invention; Fig. 2 a sectional view out the structure oilFig 1 on the line 2-2 thereof; Fig. 3 a like view of the structure ofFig. l on the line 3--3 thereof; Fig. a side view of a somewhatsimplified form of column and beam connection; and Fig. 5 a view partlyin section of a column ha in a beam connection and bracket on one sidethereof.

The column comprises the outer casing l of steel tubing or cast iron andis slotted 2 2, the points the conned tions are to be made. the formshown in Figs. 1, 2 and 3 the slots are not diametrically opposed. A tieplate 3 is at l so its end portions are parallel but oil-set and isprovided with notches 5-5. The plate 8 is pushed through the slots 2-2with the notches 55 engag the upper ends of the slots and wedges ti 8are driven into lower ends or the slots to force the tie plate up intofirm conwith the casing, the notches prevent ing lateral movement. Thewedges and plates, or either, may be welded to the casing desired.

'llnder each upper slot and alined therewith is a second slot ?-=7.Brackets 8-8 are hooked therein. These brackets have a shell 9, web 10and hook-like projections 11 7 slot. This bracket and wedge may also bewelded to the casing it deslred. The column is then inverted and tilledwith plastic material such as concrete which not only till desired. Thetops of these floor beams are generally flush with the top of thecolumn.

L another column 15' is to be superimposed a sandwich plate 16, providedwith a central opening, is laid on or secured to the top'ot'the lowercolumn and a dowel pin 17 passes through the plate aperture and engagesthe plastic filling in the upper and lower columns. The top plate 16 maybe the same size as the columns or larger, and it square, as shown inFig. 3, will form substantially a continuation of the upper flanges orthe tloor beams.

It will be noted that the bend l in the tie plate 3 permits the beamsla-1t to substantially aline the middle of the column so that the loadis evenly borne.

If a third floor beam or a single beam is to be attached the upper andlower alined slots 18 and 19 are cut at the proper places and a bracket20 and tie plate 21 are inserted in the slots and secured as beforedescribed. The tie plate 21 does not, in this case, pass entirelythrough the casing.

In the form shown in Fig. i the tie plate 22 is placed in slots in thelower part ol the upper column 23 and the sandwich plate 24 is placed onthe top of the lower column 25. By this construction the floor beamsrest on bracketslon the lower column and are cured to atie plate in theupper column uniting the two columns. The dowel 26 may be used or not asdesired.

ln Fig. 5 l have also shown how wich plate the size of the lower columnmay have column of lesser diameter supernaposed upon it.

l. A building column comprising a casing provided with a slot, a notchedtie plate ontering said slot and extending partly within and partlywithout the casing and adapted to engage the side of a floor beam, the

notch in the tie plate engaging the slot end,

a bracket secured to the casing below tie plate adapted to carry a doorbeam.

2. A. building column comprising a provided with upper and lower slots,a

notched tie plate entering the upper slot Mill with the notch engagingthe slotend, a bracket in the lower slot, a hook on said bracket withinthe casing and plastic Inaterial within the casing.

to the notch whereby the notch and slot are forced together, and abracket secured to the casing below the tie plate.

4t. A building column comprising a casing proyided with opposed, alinedslots, a notched tie plate extending through the slots and casing andbeyond the latter with the notches engaging the casing, wedges in theends oi? the slots opposed to the notches and forcing the notches intoengagement with the slot ends, brackets secured to the casing below thetie plates and a filling of plastic material within the column.

5. A building column comprising a casing provided with upper and loweropposed, alined slots, a notched tie plate extending through the upperslots and casing and extending beyond the latter with the notchesengaging the slot ends, brackets, each having inner hook-like partsengaging the lower slots below the tie plate and a filling of plasticmaterial within the casing.

6. A building column comprising a casing provided with slots slightlystaggered with respect to one another but substantially opposed, a tieplate having a bend therein with its ends substantially parallelextending through the slots and casing and beyond the latter with thebend inside the casing, brackets secured to the casing below the tieplate and a filling of plastic material within the casing.

7. Building construction comprising a col= umn casing provided withopposed slots, a notched tie plate in the slots and extending throughand beyond the casing with the notches engaging the slot ends, a bracketand plate below the column and a second column under the first carryingthe bracket and plate, said bracket and tie plate being adapted to besecured to a "floor beam whereby the floor beam is secured to both theupper and lower columns securing the two together In testimony whereof lhave hereunto subscribed my name.

JUHN LALLY.
